What do you mean by disrupted here? And don't you have to stop riding a bicycle or driving a car eventually too? Endurance racing, which is what they're actually talking about as they care about "making time", is a sport that also appears almost identically in cycling and driving. And in all those contexts it's just an elective hobby that helps paint a picture about pacing, goals, and burnout. It's not about transportation at all. But as far as running goes for transportation, it's 500,000 year old technique that ultimately requires no manufacturing or contraptions and runs on foraged berries. Other options may creep into use for a millenia or two, but it's not going anywhere.
